Samsung‘s Gear S family has been growing at a steady rate ever since the first wearable made its way to wrists, and now there are two new additions to welcome.

Samsung has officially unveiled the Gear S3 Frontier and Classic variants. There’s no Android Wear on these new devices, though, as Samsung has once again opted to use its own Tizen operating system. As far as other features go, the Gear S3 (both variants) includes a 1.3-inch 360×360 full color, always-on Super AMOLED round display. It also boasts a Corning Gorilla Glass SR+ panel, which is designed specifically for wearables.

The Gear S3 is a bit bigger than the Gear S2, measuring in at 46 x 49 x 12.9mm. Inside that case is a 1GHz dual-core processor, 768MB of RAM, 4GB of built-in storage, and a battery that is measured in at 380mAh. According to Samsung, that means the Gear S3 will last up to four days on a single charge.

There’s also a heart rate monitor on board and plenty of other sensors. The Gear S3 boasts LTE connectivity, Bluetooth 4.2, Wi-Fi, GPS/Glonass, a built-in speaker, and NFC and MST support so that Samsung Pay can be used as well for mobile payments. The Gear S3 is also IP68-rated, so it’s resistant to water and dust.

Both variants include the rotating bezel introduced with the Gear S2. Gear S3 owners will be able to accept or reject calls as needed, and can even snooze an alarm right from their wrist. Both models also support 22m watch bands.

To get the Gear S3 to connect to your Android phone, it needs to support Android 4.4 or later and have 1.5GB of RAM or more.

Samsung isn’t forthcoming about a release date or pricing for either Gear S3 model. However the U.S. press release confirms that the Gear S3 Frontier will launch later this year at AT&T, Verizon Wireless, and T-Mobile.
